NAME¶
Net::Frame::Layer::SLL - Linux cooked capture layer object
SYNOPSIS¶
use Net::Frame::Layer::SLL qw(:consts);
# Build a layer
my $layer = Net::Frame::Layer::SLL->new(
packetType => NF_SLL_PACKET_TYPE_SENT_BY_US,
addressType => NF_SLL_ADDRESS_TYPE_512,
addressLength => 0,
source => 0,
protocol => NF_SLL_PROTOCOL_IPv4,
);
$layer->pack;
print 'RAW: '.$layer->dump."\n";
# Read a raw layer
my $layer = Net::Frame::Layer::SLL->new(raw => $raw);
print $layer->print."\n";
print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
if $layer->payload;
DESCRIPTION¶
This modules implements the encoding and decoding of the Linux cooked capture
layer.
See also
Net::Frame::Layer for other attributes and methods.
ATTRIBUTES¶
- packetType
- Stores the packet type (unicast to us, sent by us
...).
- addressType
- The address type.
- addressLength
- The length of the previously specified address.
- source
- Source address.
- protocol
- Encapsulated protocol.
The following are inherited attributes. See
Net::Frame::Layer for more
information.
- raw
- payload
- nextLayer
METHODS¶
- new
- new (hash)
- Object constructor. You can pass attributes that will
overwrite default ones. See SYNOPSIS for default values.
The following are inherited methods. Some of them may be overridden in this
layer, and some others may not be meaningful in this layer. See
Net::Frame::Layer for more information.
- layer
- computeLengths
- computeChecksums
- pack
- unpack
- encapsulate
- getLength
- getPayloadLength
- print
- dump
